Process forthe carbonylation of alkanols and/or ethers at elevated temperature and pressure in the presence of a Group VIII metal compound and pentachlorobenzenethiol and/or salts thereof, using a pentachlorobenzenethiol compound : Group VIII metal compound molar ratio of not more than 10. The process is of special interest for the production of methyl acetate from methanol using an active, iodine-free catalytic system.
